Title: Optical equipment provided with image shaking correcting function and interchangeable lens
Inventor: IMADA SHINJI
IPC: G03B17/14
Filed: 1997-01-28
Abstract: PROBLEM TO BE SOLVED: To execute an optimal image shaking control action for a converter which is attached by respectively changing the correction characteristic of image shaking when the first or the second converter for changing an optical characteristic is attached. SOLUTION: A shaking correction system 102 is provided with a shaking sensor 106 and a shaking correction driving system 108 driving a correction lens based on a driving signal calculated by a lens microcomputer 101 based on the output of a position sensor 107 and correcting the image shaking. By the lens microcomputer 101, the state of the signal passed through communication lines 109f-109h for extenders is confirmed so as to discriminate the type of the attached extender. When the extender of 1.4 magnification is attached, for example, an integration characteristic being identical to the integration characteristic without the extender is set because the magnification is comparatively low. When the extender of 2 magnification is attached, the integration characteristic obtained by increasing a cut-off frequency is set in order to suppress a seasickness phenomenon.

Title: Program timer

IPC: G04G15/00
Filed: 1978-03-13
Abstract: PURPOSE: To make it possible to manually render the main circuit of a TV receiver set conductive and inconductive by brining a timer relay into an inconductive condition with the use of a reset switch which is to be turned on and off in response to a main switch.  
     CONSTITUTION: When a reset switch 61 which is to be turned on and off in response to a main switch 2, a reset circuit 6 detects this to transmit pulsating voltages to a signal line 62. Since these voltages are fed through an OR circuit 7 and a signal line 71 to the reset terminal of an FF 33, this FF 33 reverses its condition to render the timer relay 4 inconductive through a relay drive circuit 41. As a result, even if a timer circuit 3 is in its timer operation, a main circuit 5 can be rendered inconductive by such a manual operation as brings the switch 2 from conductive into inconductive conditions.

Filed: 1989-02-06
Abstract: PURPOSE:To effectively start by narrowing a last pulse width when a counterelectromotive force of a stator coil started by inputting a predetermined number of pulses to an exciting pattern generator is waveform-shaped to accelerate a rotor. CONSTITUTION:Pulses from an astable multivibrator 1 are counted by a counter 3, rectangular exciting patterns U-W are generated from a generator 4, and input to a converter 5. Then, it is applied to the stator of a DC motor 8 via a motor driver 7 to control it in an open loop. Thereafter, the counterelectromotive force of the stator is detected by a detector 19, filtered by a filter 9, phase-shifted by a phase shifter 10, amplified by amplifier 11, and input to the converter 5. A speed is detected from the output of the amplifier 11 by a detector 12. If it becomes a predetermined value or more, the constant of the filter 9 is //instructed to be converted by an instruction unit 13, and a mode switching command of a mode switching circuit 5a is instructed by an instruction unit 6. When the counter 3 counts a predetermined number of pulses, it narrows the width of a final pulse to convert it at a high speed of the rotor with high counterelectromotive force. Thus, it is effectively started and smoothly accelerated.

Title: Engine valve gear
Inventor: KAWAI HIROYUKI
IPC: F01L13/00
Filed: 1996-02-15
Abstract: PROBLEM TO BE SOLVED: To suppress the uneven wear of a stem tip part so as to improve the life of a stem by providing a relative movement regulating means for regulating relative movement between a body and a slider and bringing the slider moved in the axial direction of an intake/discharge valve and the stem tip part into contact with each other. SOLUTION: An engine valve system is provided with a relative movement regulating means for regulating relative movement between bodies 20, 23 and 24 and a slider 32. When relative movement is regulated, after a cam 11 is engaged with the body 20, the body 20 is moved together with the slider 32 and a stem 15 against the pressing force of a first spring 18 and thus an intake/ discharge valve 14 is opened/closed. After the regulation of the relative movement is released, the intake/discharge valve 14 is placed in a constantly stopped state. That is, since the slider 32 moved in the axial direction of the intake/ discharge valve 14 and the stem tip part are contacted with each other, the load of a direction orthogonal to the axial center of the stem 15 is prevented from being applied on the stem tip part. Thus, shaving of the stem tip part is prevented.

Abstract: PURPOSE:To form intake/scavenging ports without gnawing a piston, by piercing a communication passage between a space section and a crank chamber through a cylinder block in the vertical direction. CONSTITUTION:Upon compression stroke during which a piston 6 moves upward, the pressure in a crank chamber 7 is made negative so that a reed valve 36 opens to introduce a mixture into the crank chamber 7 through an intake port 41. Due to the ignition of a spark plug 9, the mixture in a cylinder chamber 2 is burnt to move the piston 6 downward so that the pressure of the mixture introduced into the crank chamber 7 is raised. As a result, the reed valve 36 returns to its original position by its resiliency to close an intake-air passage 34, and when the top surface of the piston 6 initiates to meet the upper edges of main scavenging ports 14, 15 and counter-scavenging port 42, the mixture is fed to the upper section of the cylinder chamber 2 through the main scanvenging ports 14, 15 and the counter-scavenging port 42 to replace the burnt gas which is then discharged through an exhaust port 12.

IPC: H02P29/00
Filed: 1997-01-27
Abstract: PROBLEM TO BE SOLVED: To suppress fine vibration at stop time and to increase positioning precision at the stop time by correcting position deviation as a predetermined constant and performing position control. SOLUTION: A position deviation decision unit 122 inputs a position command Pref(i) and position deviation Pe(i) and outputs signals α (α>1) and β (β<0) when absolute values are all less than N pulses and an increment value dPref(i) is zero, and signals α=1 and β=0 when not. An adder 123 adds the position deviation Pe(i) and signal β together, and a coefficient multiplier 124 which receives the resulting signal multiplies by a coefficient Kp and outputs a speed command Vref(i). When the position deviation Pe(i) is within ±1 pulse and stops, it stops at one of three pulses having pulse width of ±1 pulse, 0 pulse, and -1 pulse. Consequently, the performance of the position controller is improved to increase the practicability.
